摘要: Tokens/keys are produced for wireless communications. These tokens/keys are used for watermarks, signature insertion, encryption and other uses. In one embodiment, contextual information is used to generate tokens/keys. The tokens/keys may be derived directly from the contextual information. The contextual information may be used in conjunction with other information to derive the tokens/keys. Tokens/keys may be exchanged between transmit/receive units. The exchange of these tokens/keys may be encrypted.
摘要翻译: 产生用于无线通信的令牌/密钥。 这些令牌/密钥用于水印,签名插入,加密和其他用途。 在一个实施例中,使用上下文信息来生成令牌/密钥。 令牌/密钥可以直接从上下文信息导出。 上下文信息可以与其他信息一起使用以导出令牌/密钥。 令牌/密钥可以在发送/接收单元之间交换。 这些令牌/密钥的交换可以被加密。
